Question

a body is moving with a uniform acceleration travels 24m in the 6th second and 44m in the 11th second. find 1). acceleration 2). uniform velocity of the body

Answer 1

The "average speed over one second" increases by 20 m/s in 5 seconds. The acceleration is therefore 4.0 m/s^2.

There is no uniform velocity, since it is accelerating. Perhaps you did not state the question correctly.
